Occurrence and functional compatibility within Enterobacteriaceae of a tRNA species which inserts selenocysteine protein

The selC gene from E. coli codes for a tRNA species (tRNA super(S)dU super(e)dC super(r)dA which is aminoacylated with L-serine and which cotranslationally inserts selenocysteine into selenoproteins. By means of Southern hybridization it was demonstrated that this gene occurs in all enterobacteria t...

Description
Summary:The selC gene from E. coli codes for a tRNA species (tRNA super(S)dU super(e)dC super(r)dA which is aminoacylated with L-serine and which cotranslationally inserts selenocysteine into selenoproteins. By means of Southern hybridization it was demonstrated that this gene occurs in all enterobacteria tested. To assess whether the unique primary and secondary structural features of the E. coli, selC) gene products are conserved in that of other organisms, the selC homologue from Proteus vulgaris was cloned and sequenced.
